Turns a Raspberry Pi into a cheap, universal & web-enabled Reflow Oven Controller. Of course, since it is basically just a robot sensing temperature and controlling environmental agitators (heating/cooling) you can use it as inspiration / basis when you're in need of a PID based temperature controller for your project. Don't forget to share and drop a link, when you do :)
- Raspberry Pi (Rev 2B)
- MAX 31855/6675 Cold-Junction K-Type Thermocouple
- GPIO driven Solid-State-Relays/MOSFETs
We've tried to keep external dependencies to a minimum to make it easily deployable on any flavor of open-source operating system. If you deploy it successfully on any other OS, please update this:
Currently tested versions
$ sudo apt-get install python-pip python-dev libevent-dev $ sudo pip install ez-setup $ sudo pip install greenlet bottle gevent gevent-websocket
$ emerge -av dev-libs/libevent dev-python/pip $ pip install ez-setup $ pip install greenlet bottle gevent gevent-websocket
Raspberry PI deployment
If you want to deploy the code on a PI for production:
$ pip install RPi.GPIO
This only applies to non-Raspbian installations, since Raspbian ships RPi.GPIO with the default installation.
If you also want to use the in-kernel SPI drivers with a MAX31855 sensor:
$ sudo pip install Adafruit-MAX31855
$ git clone https://github.com/apollo-ng/picoReflow.git $ cd picoReflow
All parameters are defined in config.py, just copy the example and review/change to your mind's content.
$ cp config.py.EXAMPLE config.py
Autostart Server onBoot
If you want the server to autostart on boot, run the following commands
sudo cp /home/pi/picoReflow/lib/init/reflow /etc/init.d/ sudo chmod +x /etc/init.d/reflow sudo update-rc.d reflow defaults
Open Browser and goto http://127.0.0.1:8080 (for local development) or the IP of your PI and the port defined in config.py (default 8080).
